110Ten or More Good Reasons to

Choose Netafim PC Spray Stakes

Superior Wetting of the Soil MixImproves plant quality and conserves resources

2Uniform Watering from the First Pot to the LastImproves plant quality, simplifies design and controls system costs

Netafim PC (Pressure Compensating) Spray Stakes were built from the beginning to fill the needs of the nursery grower. The spray pattern angles downward - just enough - to keep the spray on the soil and not flying into or over the wall of the pot. Water flying out of the pot is wasted. Water that hits the side of the pot typically runs down the side and out the bottom of the pot and is not effective in wetting the soil mix.

Water retained by the soil mix is the most important measure of the effectiveness of a spray stake. A poor spray pattern may look good to the eye, but in fact does not apply water uniformly over the soil surface and results in poor water retention. The Netafim spray pattern provides maximum water retention by the soil mix - exactly what the plant needs. An additional benefit of the excellent wetting pattern is the uniform activation of top-dressed fertilizers. The result is superior plant growth and more efficient use of water resources, and fertilizer if liquid feed is being used.

Good Wetting PatternEven distribution means little or no water and fertilizer will be lost from drainage and the roots will grow evenly throughout.

Poor Wetting PatternWhen water is not evenly distributed over the surface of a container, overwatered ‘hot spots’ develop and water channels quickly through the mix and drains away before the plant can use it.

Have you ever measured the difference in the amount of water the plants closest to the valve get compared to those furthest from the valve? It might be much more than you think and it adds up over time.

In a non-pressure compensating design, the spray stakes at the beginning of the line have a higher pressure and supply more water than those at the end of the line. Therefore, plants at the beginning of the line receive more water than they need by the time the plants at the end of the line are sufficiently watered. Each time the field is watered these differences add up and eventually some plants can outgrow others, resulting in a lack of uniformity and less than a top-quality yield.

Netafim pressure compensating emitters have been in use for over 20 years and can now be used in spray stake systems. As a result, Netafim PC Spray Stakes ensure every pot in the entire system receives exactly the same amount of water. This eliminates the need to overwater some plants to be sure the driest plants receive enough water to thrive. This water savings is typically between 5% and 20% and can be even more.

3Have your ever noticed how much mist non-compensating spray stakes produce? It is especially evident on a windy day, as that water is wastefully blown away. One more advantage of pressure compensation is that it conserves water. Even at high pressures, up to 60 psi, the pressure compensating mechanism and the downward water spray of the Netafim PC Spray Stake eliminate misting.

4Prevents Draindown Onto Lowest PlantsAvoids plant stress from drowning

Everyone knows that water flows downhill - just ask the plants at the bottom of a hill. Downhill flow is exactly what happens after every irrigation in systems without Netafim’s check valve feature. All the water in the pipe drains out through the lowest spray stakes downhill. When large pipes are used, this can be a very large volume of water. One hundred feet of 1” pipe contains 15 gallons of water and one hundred feet of 4” pipe contains 65 gallons of water. When tens, or hundreds of gallons of water flow out onto the low lying plants after each irrigation, the plants eventually become stressed by excess water.

This problem is eliminated with Netafim’s built-in check valve feature. The check valve prevents the system from draining (up to 10 feet of elevation) after each irrigation.

Downward Water SprayEliminates misting.

Prevents Water from Blowing Away in the WindSaves water while nearly eliminating misting

Water Drains to the Lowest PlantsWith ordinary spray stakes, at the end of every watering cycle, the pipes drain into the lowest lying plants.

Check Valve Prevents DraindownWith the Netafim Check Valve feature the pipes stay full and do not drain into the lowest lying plants.

6Simplifies Design LayoutReduces system costs

Pressure compensation has advantages beyond the improvement in watering uniformity. It also simplifies the design layout and allows you to reduce system costs with:

• Longer runs - see Design Help section for specific recommendations

• Smaller supply pipes - pipe downsizing usually pays for the pressure compensation feature

• Fewer sub-mains - a very significant cost, especially in areas of difficult trenching

• Fewer valves - longer runs mean a simpler layout requiring fewer system components

7Simple, Secure Shut-OffPrevents water waste and accidental close-offs

The side-mounted, secure shut off is easy and fool-proof. For close-off, remove the nipple and tubing from the top of the spray stake and attach it to the side of the spray stake. This provides a clear, visual indication – even from a distance - if a unit is in the on or off position.

Simple Shut-Off MechanismRemove tubing from top and attach to the side.

5Spray Patterns Designed for Nursery ContainersPick the spray pattern that is right for your plants

For simplicity, some growers place the spray stake near the edge of the pot, making the single-sided spray stake the best selection. Other growers prefer the advantages created by our unique ‘bow-tie’ double-spray pattern:

• Doubles the size of the spray pattern, useful for optimized wetting in very coarse mixes, or large pots. One spray stake can do the work of two or more traditional spray stakes.

• Allows positioning of the spray stake near the stem of the plant. This placement minimizes wetting of the base of the stem, a vulnerable point for some plant species.

8Adaptable to All Soil Media TypesStake or rod mount options available

All flows are available in both a 7” stake and a rod mount (12 gauge metal rod) version for more application options and greater flexibility. Rod mount spray stakes are ideal for:

• Deeper insertion into coarse bark mix for added stability

• Greater allowance for height adjustment to increase size of wetted pattern

• Customizing the height of the spray stake

9Full Range of FlowsChoose the flow best suited to your water source and plant needs

Netafim PC Spray Stakes are color-coded and available in four flow options: 3.2, 6.6, 7.9 and 10.6 GPH. Color-coded spray stakes make it easy to identify the flow from a distance. Based on your water source and plant needs, you can choose the best flow for your nursery pots.

10Low MaintenanceLowers cost of operation

Some systems are inexpensive to purchase initially, but as they age the cost of maintenance begins to outweigh the initial low cost. Netafim PC Spray Stakes are designed to avoid the plugging that occurs in many lower cost stakes. Each individual stake assembly has an inlet filter to prevent debris from entering. This filter is swept clean by the natural velocity of the water in the pipe. Netafim recommends appropriate central filtration for all spray stake systems but the individual inlet filter greatly reduces the incidence of field plugging from construction repair and other contaminants.

11Easy InstallationPrevents problems that increase installation costs

Quick, fool-proof installation lowers costs and prevents problems. There is no risk of mis-cutting or pushing the micro-tubing in too far as some growers experience with standard spray stakes. Simply punch a hole in the supply tube using a Netafim hole punch, insert the dripper and tubing assembly and attach the spray stake. Each assembly comes ready to use.

Selecting the Right Netafim PC Spray Stake for Your Application

Select the flow rate for the spray stake. As long as you have enough water and pressure for the

stake you select, it’s hard to go wrong. Netafim PC Spray Stakes will work in a very wide range of pot sizes (see table at right for general recommendations). Just remember, these are not strict limitations, just general guidelines. Many growers with larger pots use higher flow spray stakes while others prefer to use lower flow spray stakes and simply operate them longer.

The next consideration is how long a row or ‘run’ of pots you want to water. Lower flow spray stakes can water longer runs than higher flow spray stakes. See the Design Help section of this brochure to be sure the flow you select will be appropriate for your water resources and field configuration.

Select the spray pattern.

Most flow models offer both a single and a double spray pattern. The double spray pattern is selected when the stake will be placed closer to the trunk of the tree than the side of the container. Here it will wet more soil than the single spray and can be positioned to minimize wetting the base of the trunk.

Select the spray stake mounting option. Choose either the standard stake or the rod mount stake.

Growers choose the rod mount generally for these reasons:

• For very coarse bark planting mixes a longer stake is needed to provide good stability

• To raise the spray stake up a bit more to create a larger spray pattern

• For the widest range of height adjustability

Design Help for Netafim PC Spray Stakes

Determine how many spray stakes you can operate at the same time. Use the Zone Flow chart to establish how much water it would take to operate one zone of spray stakes with the spray stake flow rate you have selected. You do not need to operate the maximum amount, but do not exceed the maximum. If the amount of water required exceeds the amount you have available, you might reduce the zone size or consider using a lower flow spray stake. Suggestion: Build a table listing the flow of each zone you wish to operate.

Step1

Determine how long a row or ‘run’ you can make with each line of spray stakes. This is influenced by several factors and you can balance them according to your priorities. The Length of Run Considerations chart demonstrates how the influencing factors are related.

When the spacing for the spray stakes has been determined, you are ready to select the pipe size and operating pressure:

• There are four Length of Run charts, one for each flow rate. Select the chart based on the flow rate you will be using (see pages 9 and 10).

• Select the spacing to be used for the spray stakes.

• Reading across to each pipe size, find the maximum length of run (in feet) available for several inlet pressures (in psi). Each option also includes the number of pots for that length of run (shown in parenthesis).

Note: The Length of Run charts do not account for slope. Although the pressure compensating feature of the PC spray stake will ensure that all flows will be the same, it is still necessary to operate the spray stake with a minimum of 22 psi and a maximum of 55 psi. If you are working with slopes, it is advisable to use a qualified Netafim Dealer to assist you in your design to be certain you have a pressure balanced system.

ValvesNetafim offers Valve solutions for nearly every need. The Valves chart shows the most common valves used in spray stake systems and includes electric solenoid valves for automatic systems (used with a controller) and pressure reducing valves to manage system pressure in a manually operated system with high pressures (over 60 psi).

Filters Filter options include disc, screen, sand media and hydrocyclones (for sandy wells). Some filters are for specific water applications and some are multi-purpose. Excellent options are available for both well water and surface water sources. Recommended filtration is 120 mesh.

Water MetersWater Meters are the simplest and best ‘window’ into what is going on in your system. The key to a long lasting, low maintenance system is through preventative maintenance. A periodic check of the water meter can tell you when it’s time for maintenance.

AutomationGrowers considering automation should visit our website or call 888-NETAFIM to request brochures relating to Automation Products. With a variety of controllers to fit many needs; from 16 to 600 valves with standard multi-wire, dual strand cable, stand-alone, radio control or central control, you can start with simple or richly featured programs and immediately realize the full potential of an automated system.
